St George’s Greening
The
Church Buildings are used by an increasingly growing number of
organisations from the surrounding community which places its own
demands on the running costs and energy use of the property. During the
day there are school groups from adjacent schools using them for
curriculum activities, there are Yoga classes, dance classes, 2 choirs,
Probus, Callisthenics, a Cycling Club, Concerts, Parties and Family
Gatherings and a myriad of other users.
As a Christian community we
believe that by better conserving and utilising our precious water and
energy resources we are expressing our gratitude to God for the wonders
of the world created for all living beings, and our sense of
responsibility to do what we can to care for this beautiful world which
nourishes life.
We have tried to reduce our energy and water demands in the following areas:
Lighting
External and internal lighting uses high efficiency fluorescent or low voltage globes wherever possible.
The
external lights were replaced in 2007 by retro fitting 28 and 13 watt
Ecobright T5 lamps and reducing the power requirement for each
large fitting by 2x12w or about 30% overall. The original
lighting was already saving costs by using fluorescent tubes. The
entire building is illuminated using less energy than a 1000w spot or
halogen light.
Heating
The
inefficient heating system under the pews in the church was replaced a
number of years ago with Thorn Halogen heaters, wall mounted which more
than halved the running costs of the old system.
Hot Water System
The
previous electrical hot water storage system was replaced with a
Quantum split system commercial unit which supplies the washrooms and
the 3 kitchen facilities in the halls and offices. This was
achieved with a Sustainability grant from the Banyule Council of $2000
and Commonwealth Government Energy Credits of about $5000 leaving the
Church to pay about $800
When the new kitchen was built the
problem of the loss of water temperature in the 25 meters of pipe
between the storage heater and the kitchen was overcome by the
installation of a reticulation pump so that hot water is delivered
almost immediately at the kitchen taps without loss of water.
Rain Water collection
St
George’s applied for and received a Commonwealth Government Grant to
fund the harvesting of rainwater from our massive roof area.
The
water will be collected in bladders and stored under the church to be
used for the toilet systems and garden watering. The grant
received also includes the replacement of outdated toilet pans and
flushing systems.
We anticipate that we will be entirely self
sufficient for all our watering requirements with the exception of
kitchen and hand washing, and save at least 200,000 litres of water a
year.
Our future goal is
to install solar panels for electricity generation to reduce even
further our demand on the power grid and perhaps provide green power
into the system.
